Context is always key with these kinds of reactions. Few people feel that hex editors are unnecessary, they probably don't know they exist. The reason you see this sort of thing with Kubernetes is that for whatever reason its hype over-extends its problem domain and many times people who do not need them receive the suggestion (or insistence) to use them. If someone were to tell you to use a hex editor to edit your JavaScript, you might very well reach the conclusion that hex editors are a cult, and useless. Someone might then point out that there are actual completely justified use cases for them. That's what I see happening here: whether it be indirect (tons and tons of blog posts and articles about moving to Kubernetes), or direct (an employee insisting that the company's infrastructure be moved to Kubernetes), or a mix (starting to see Kubernetes experience as a requirement for jobs that probably doesn't need it), all of a sudden you have the backlash against the perceived "Kubernetes for everything" culture (which in turn looks like a weird straw man to people who actually know what its for).
